Oooo I loved the original doujin so I'm excited for this! Love the author's artwork too so I'm glad they caught the attention for a serialization.
That being said I preferred the original premise better. It was more scandalous and fun. There was more sexual tension in the original 2 chapters too and the vibe of the two flowed better. I think Touko came across a lot flirtier in the original too so the contrast between home!Touko and work!Touko was a lot sweeter.
Ch 1 here is a bit awkward and clunky, but maybe it's just because they're trying to get all the stuff from the doujins out of the way so the real story can begin.
Anyway kinda sad about the changes, but I understand that they needed to tone down the child predator vibes for the (more) general public.
